Voters vote for individual candidates in single districts and for a prefered ruling party for all districts. The support for parties is determined either by adding the votes for individual candidates or from a separate party vote, then "top-up" seats are allocated at a regional or national level to achieve a more proportional result. Mixed member systems are used in [[Germany]], [[Italy]] and [[New Zealand]] where a party has to reach a 5% threshold in order to get into the House.
